The State of Health and Health Care for LGBTQ+ Veterans: Differences Among Sexual and Gender Minority Veterans, by Identity and State Policy Climate, 2015-2021.

The U.S. government has affirmed commitments to improving health and well-being for lesbian, gay, bisexual, transgender, queer, and other sexual and gender minority (LGBTQ+) veterans, who may have distinct needs and challenges when accessing timely and appropriate health care. To date, there are limited data about potential health disparities among LGBTQ+ veterans that examine differences by both sexual identity and gender identity. Understanding the nature and magnitude of disparities among LGBTQ+ veterans is critical for targeted efforts to improve their health and well-being. The authors of this study use nationally representative data from 2015-2021 from the Behavioral Risk Factor Surveillance System to compare the age-adjusted prevalence of health-related outcomes across multiple domains (health care access and affordability, general health, substance use, and chronic conditions) for sexual and gender minority veterans with that of their heterosexual and cisgender veteran peers. LGBTQ+ veterans showed poorer health-related outcomes in multiple domains than their heterosexual and cisgender peers, including in terms of healthcare affordability, mental health, chronic cardiovascular conditions, and chronic respiratory conditions. The authors also examine associations between state LGBTQ+ policy climates and health-related outcomes among LGBTQ+ veterans. Among LGBTQ+ veterans, living in a state with a more favorable (versus negative) LGBTQ+ policy climate was associated with several health indicators (e.g., having health insurance, lower smoking rates). The authors then discuss implications for ongoing efforts to improve health and well-being for LGBTQ+ veterans, including sustained actions to ensure that all LGBTQ+ veterans are able to access necessary care and use the full scope of benefits for which they are eligible.

Unveiling distinct kinematic profiles among total knee arthroplasty candidates through clustering technique.

BACKGROUND: Characterizing the condition of patients suffering from knee osteoarthritis is complex due to multiple associations between clinical, functional, and structural parameters. While significant variability exists within this population, especially in candidates for total knee arthroplasty, there is increasing interest in knee kinematics among orthopedic surgeons aiming for more personalized approaches to achieve better outcomes and satisfaction. The primary objective of this study was to identify distinct kinematic phenotypes in total knee arthroplasty candidates and to compare different methods for the identification of these phenotypes. METHODS: Three-dimensional kinematic data obtained from a Knee Kinesiography exam during treadmill walking in the clinic were used. Various aspects of the clustering process were evaluated and compared to achieve optimal clustering, including data preparation, transformation, and representation methods. RESULTS: A K-Means clustering algorithm, performed using Euclidean distance, combined with principal component analysis applied on data transformed by standardization, was the optimal approach. Two unique kinematic phenotypes were identified among 80 total knee arthroplasty candidates. The two distinct phenotypes divided patients who significantly differed both in terms of knee kinematic representation and clinical outcomes, including a notable variation in 63.3% of frontal plane features and 81.8% of transverse plane features across 77.33% of the gait cycle, as well as differences in the Pain Catastrophizing Scale, highlighting the impact of these kinematic variations on patient pain and function. CONCLUSION: Results from this study provide valuable insights for clinicians to develop personalized treatment approaches based on patients' phenotype affiliation, ultimately helping to improve total knee arthroplasty outcomes.

Discrimination experiences and problematic alcohol and cannabis use in young adulthood.

BACKGROUND AND OBJECTIVES: Limited research has examined how discrimination in young adulthood relates to substance use. We examined how multiple and specific types (e.g., race-based) of experiences of unfair treatment are related to problematic alcohol and cannabis use. METHODS: We analyzed cross-sectional data from a diverse cohort of young adults (mean age 24.7) predominantly residing in southern California (n = 2303) to examine associations of multiple (count) and specific experiences (race-, sexual orientation-, gender-based) of perceived everyday discrimination with self-reported alcohol and cannabis use outcomes (consequences, use disorders, and solitary use). We also tested interactions between the three specific discrimination experiences and sociodemographic characteristics (e.g., race-based discrimination × race/ethnicity). RESULTS: In this diverse sample (e.g., 47% Latinx/o and 22% Asian; 22% sexual/gender diverse; 56% female) of young adults, about 46% reported up to four different discrimination experiences and 27% reported race-, 26% gender-, and 5% sexual orientation-based discrimination. Race- and gender-based discrimination and experiencing more types of discrimination were associated with worse cannabis use outcomes. Race-based discrimination was associated with fewer alcohol consequences and lower Alcohol Use Disorders Identification Test (AUDIT) scores. Associations with sexual orientation-based discrimination and the interactions were not significant. DISCUSSION AND CONCLUSIONS: Findings build on limited research on associations of discrimination with cannabis use in young adults. More work is needed to understand the mechanisms by which discrimination influences drinking behaviors. SCIENTIFIC SIGNIFICANCE: This study advances the field by examining the unique contributions of specific and multiple types of discrimination experiences in young adulthood, a critical developmental period in which substance use peaks.

Tibial Slope Is Not Associated With Implant Migration Following Cemented Total Knee Arthroplasty With a Single Implant Design.

BACKGROUND: The influence of tibial slope on tibial component migration following total knee arthroplasty has not been widely studied, although excessive posterior slope has been implicated in some failures. As implant micromotion measured with radiostereometric analysis can indicate successful fixation, the purpose of this study was to determine the associations between tibial slope, tibial component migration, and inducible displacement. METHODS: Radiostereometric analyses at 6 visits over 2 years quantified implant migration for 200 cemented total knee arthroplasties. Longitudinal data analysis examined the influence of postoperative tibial slope on implant migration (overall maximum total point motion (MTPM) migration and anterior-posterior tilt migration), accounting for age, sex, and body mass index. The correlations of tibial slope with 1-year migration, continuous migration, and inducible displacements were also examined. Additionally, the amount of change in slope was compared to migration. RESULTS: The mean posterior tibial slope was 8.0° (standard deviation [SD] 3.8°) preoperatively and 3.8° (SD 3.1°) postoperatively, with a mean reduction in slope of 4.2° (SD 4.7°). Postoperative tibial slope (range 14.0° posterior slope to 3.4° anterior slope) was not associated with longitudinal overall migration (P = .671) or anterior-posterior tilt migration (P = .704). There was no association between postoperative tibial slope and migration at 1 year postoperatively (P = .441 for MTPM migration, P = .570 for tilt migration), change in migration from 1 to 2 years (P = .951), or inducible displacement (P = .970 MTPM, P = .730 tilt). The amount of change in tibial slope was also not associated with migration or inducible displacement. CONCLUSIONS: Residual and change in postoperative tibial slope were not associated with implant migration into tilt or overall migration, or inducible displacement for a single implant design. These findings support positioning tibial implants in a range of slopes, which may support patient-specific approaches to implant alignment.

True Confessions of Neutral Mechanical Disciple-How I Learned to Love a Patient-Specific Target.

INTRODUCTION: Classical neutral mechanical alignment in total knee arthroplasty (TKA) has been a standard paradigm, while more recently, other alignment schemas, such as kinematic, individualized, and functional, have been explored. This study aimed to investigate the effect of three-dimensional (3D) computed tomography (CT)-based surgical robotics inputs on a classically trained surgeon's TKA component positions and alignment targets over time. MATERIALS AND METHODS: Data from 1,394 consecutive robotically-assisted TKAs by a single surgeon from 2016 to 2020 were analyzed. Metrics collected included pre-balance planned implant component positions, final planned implant component positions after soft tissue balancing, and constitutional alignment from CT scans. Joint line obliquity was plotted against the arithmetic hip-knee angle (aHKA) using coronal plane alignment of the knee (CPAK). Three categories of alignment strategy were defined: true mechanical alignment (tMA), adjusted mechanical alignment (aMA), and no mechanical alignment (noMA). RESULTS: A shift to overall varus component positioning was observed over the years. Joint line obliquity according to CPAK showed a wider spread in later years, and the distribution of tibial and femoral coronal alignment angles expanded over time. CONCLUSION: The study revealed a change in alignment targets and final positioning of components away from neutral biomechanical axes in a large volume of TKAs by a single, classically trained surgeon over five years of using a robotic arm-assisted TKA system with CT-based planning. The most dominant factor for this change was the use of 3D CT planning, allowing the surgeon to assess patient-specific anatomy and plan accordingly. Outcome data is needed to determine if this change in behavior and surgical technique was beneficial. In summary, using a CT scan-based robotically assisted technique led to a gradual and complete shift from tMA to predominantly a non-mechanically aligned philosophy in TKA.

Measuring susceptibility to use tobacco in an increasingly complex consumer marketplace: How many questions do we really need?

OBJECTIVE: Predicting which young people are likely to use tobacco in the future is critical for prevention and intervention. Although measures for assessing susceptibility to using tobacco have fulfilled this goal for decades, there is almost no standard for the number of items that should be administered, or which items should be administered for which products. This study explored whether brief but psychometrically sound versions of commonly used susceptibility measures can adequately capture the construct relative to longer measures. METHOD: A sample of young people (N = 451; Mage = 16.5 years; 64% females; 65% White) completed 33 susceptibility items, which are designed to assess susceptibility to use different types of tobacco products (cigarette, smokeless tobacco, vaping products, and little cigars/cigarillos) of various flavors (tobacco, menthol, and sweet). RESULTS: Analysis of these 33 items indicated that asking about the likelihood of using each tobacco product class when a best friend offers it (four items in all) captures 98.5% of information that is captured using the longer set of items; asking the best friend question for each product by each flavor category (11 items in all) captures 99.7% of the information. CONCLUSIONS: Depending on research needs, tobacco use susceptibility can be measured with little loss of information by administering a limited set of items assessing the likelihood that a young person will use a tobacco product if a friend offers it for any product-flavor combination.

Does Reducing the Size of the Tobacco Power Wall Affect Young People's Risk of Future Use of Tobacco Products? An Experimental Investigation.

OBJECTIVE: A ban on tobacco power walls (in-store package displays) is unlikely in the United States because of concerns that such bans violate commercial free speech rights. This experiment evaluated the effectiveness of a more measured strategy for mitigating the influence of the power wall on young people's susceptibility to tobacco use: limiting its size. METHOD: The experiment took place in the RAND StoreLab, a life-sized replica of a convenience store. Participants (N = 275) ages 11-20 years were randomly assigned to shop in a variant of the StoreLab that had either a large (status quo), medium, or small power wall situated behind the checkout counter. Before and after shopping, participants completed measures of risk of future use of unflavored and flavored cigarettes and vaping products. RESULTS: Study condition was unrelated to future risk of smoking unflavored cigarettes, using menthol vaping products, and using sweet-flavored vaping products. Study condition was related to future risk of smoking menthol cigarettes and using unflavored vaping products; compared with exposure to a large power wall, exposure to a small power wall increased the odds of a participant's being at risk for future smoking of menthol cigarettes (odds ratio [OR] = 3.29, 95% CI [1.10, 9.83]) and the odds of a participant's being at risk for using unflavored vaping products (OR = 4.09, 95% CI [1.41, 11.85]). CONCLUSIONS: These findings call into question the viability of reducing the size of the power wall as a singular strategy for dampening its effect on young people's susceptibility to tobacco use.

Doing more with less: A proposal to advance cigarette packaging regulations in the United States.

Cigarette packages are potent marketing tools. Following guidance from the WHO Framework Convention on Tobacco Control, many countries have sought to diminish this marketing power by mandating that (1) large graphic health warnings be affixed to the packages (i.e., text warnings combined with graphic images of the health consequences of smoking) and (2) all packages be fully "plain" in their design (i.e., all packages use the same drab/bland color and font type; no brand logos, other colors, or designs are permitted). Yet, the United States lags other countries in implementing regulations designed to blunt the marketing power of cigarette packages. This is not because of a lack of effort on the part of the Food and Drug Administration, the main governmental body charged with regulating tobacco products in the United States. Rather, it is because the regulatory options that that have been advanced in the country (e.g., graphic health warnings) have not been found - yet - to be legally feasible by its courts. This commentary works through some of the conceptual, practical, and legal issues regarding packaging regulations in the United States. It considers the political and bureaucratic risks involved with issuing new regulations. The overall intent is to prompt our field to think creatively about what is realistic in this regulatory space and to offer a novel perspective that may help move the United States tobacco control community forward in its efforts to reduce the promotional power of cigarette packages.

Sober Curiosity and Participation in Temporary Alcohol Abstinence Challenges in a Cohort of U.S. Emerging Adults.

OBJECTIVE: Thus far, behavioral health research in the United States has not explored the prevalence or correlates of sober curiosity (SC; exploratory or experimental abstinence or moderation) or temporary alcohol abstinence challenges (TAACs; e.g., "Dry January"), despite significant attention in media and popular discourse. We explored these activities in a sample of U.S. emerging adults (e.g., ages 18-29), a population with higher-risk drinking behavior yet some of the lowest rates of treatment engagement for alcohol use problems. METHOD: Survey data were collected in 2021-2022 among participants (n = 1,659; M age = 24.7 years). We assessed SC awareness/engagement and past-year TAAC participation, and differences across demographics and behavioral characteristics. RESULTS: Overall, 9% of emerging adults were familiar with SC and 7% had participated in a TAAC in the past year. Half of TAAC participants reported drinking less after the TAAC, and 15% remained abstinent after the TAAC ended. SC familiarity and TAAC were both associated with past-month heavy drinking, cannabis use, higher Alcohol Use Disorders Identification Test (AUDIT) scores, more past-year alcohol and cannabis consequences, past-year substance use treatment, and greater readiness to quit alcohol. CONCLUSIONS: Both SC and TAACs may have potential to engage young people with a desire to moderate or eliminate their alcohol consumption. This may occur directly through use of these strategies or by helping them connect to additional services. Future research can help the field understand the uptake of SC and TAACs, gauge efficacy, and identify avenues to link young people to resources and interventions.

Longitudinal associations among experiences of sexual assault, posttraumatic stress disorder symptoms, and heavy drinking in young adults.

Prior research with young adults has demonstrated clear associations between experiences of sexual assault, symptoms of posttraumatic stress disorder (PTSD), and alcohol use, but most studies have been cross-sectional or have not considered multiple theoretical pathways to understand these associations. Using six waves of data from a longitudinal cohort sample of 1,719 young adults, we examined associations among experiences of past-year sexual assault (i.e., rape, unwanted sexual touching, and physical intimidation in a sexual way), PTSD symptoms, and the frequency of binge drinking over time, allowing for the exploration of symptom-induced, interpersonal risk, and substance-induced pathways for male and female participants. For both male, ßs = 2.84 to 6.55, and female participants, ßs = 2.96 to 10.1, higher prior levels of PTSD symptoms were associated with larger increases in binge drinking over time. For female participants, higher prior levels of sexual assault were associated with larger increases in PTSD symptoms over time, ßs = 3.48 to 4.25, whereas for male participants, higher prior levels of past-year binge drinking were associated with decreases in PTSD symptoms over time, ßs = -2.75 to -0.53. Continued efforts are needed to prevent sexual assault among young adults and address PTSD symptoms among those who experience sexual assault. Interventions that target binge drinking are also needed for individuals who experience PTSD symptoms, especially young adults, to address potentially hazardous drinking before problems escalate and become chronic.

Dental staff and patient attitudes about nicotine replacement therapy samples in dental care: A National Dental Practice-Based Research Network study.

OBJECTIVES: Cigarette smoking negatively affects oral health. Nicotine replacement therapies (NRT; e.g. nicotine patch or lozenge) and brief interventions (e.g. Ask-Advise-Refer; AAR) can improve cessation outcomes but are underutilized. NRT sampling (NRTS) increases NRT utilization by providing patients with samples of NRT as part of routine healthcare. Ask-Advise-Refer is a brief intervention where practitioners: ask patients about tobacco use, advise those using tobacco to quit and refer to the state quit line. The objective of this qualitative study was to explore dental care practitioners' and patients' attitudes and experiences regarding tobacco cessation treatment and perceptions of two brief intervention models, assessed separately: NRTS and AAR. METHODS: Twenty-four dental care practitioners and nine patients, recruited through the National Dental Practice-Based Research Network, participated in semi-structured telephone interviews. Interviews assessed experiences with tobacco use intervention and attitudes towards NRTS and AAR. Thematic analysis identified emergent themes related to feasibility and acceptability of NRTS and AAR. RESULTS: Practitioners varied on how they address tobacco use, from systematically to idiosyncratically. Some practitioners recommend NRT; few had prescribed it. Practitioners had favourable attitudes towards AAR and NRTS, with most believing that both interventions would be acceptable and feasible to implement. Concerns regarding AAR were time and patient resistance to discussing tobacco use. Concerns regarding NRTS were patient resistance to using NRT, side effects or medication interactions, and capacity to provide follow-up. Patients reported that oral health practitioners generally ask about tobacco use but do not provide interventions. Patients were open to discussing their tobacco use with practitioners and had favourable attitudes about NRTS. CONCLUSIONS: This formative work suggests that NRTS and AAR may be feasible to implement in dental care settings. Future studies are needed to assess the effectiveness and implementation potential of NRTS in dental care settings.

6-month migration sufficient for evaluation of total knee replacements: a systematic review and meta-analysis.

BACKGROUND AND PURPOSE: This updated meta-analysis evaluates the migration pattern of the tibial component of primary total knee replacements measured with radiostereometric analysis (RSA). We aimed to evaluate whether 6-month maximum total point motion (MTPM) values could be used instead of 1-year MTPM for RSA threshold testing and to present the pooled migration patterns for different implant designs that can be used as a benchmark. PATIENTS AND METHODS: The search included all published RSA studies on migration patterns of tibial components until 2023. Study groups were classified according to their prosthesis brand, fixation, and insert (PFI). Sub-analyses were performed to compare the mean tibial component migration patterns of different implant variables, stratified according to fixation. RESULTS: 96 studies (43 new studies), including 197 study groups and 4,706 knees, were included. Most migration occurred within the first 6 postoperative months (126 study groups: mean 0.58 mm, 95% confidence interval [CI] 0.50-0.65), followed by minimal migration between 6 and 12 months (197 study groups: mean 0.04 mm, CI 0.03-0.06), irrespective of the fixation method used. Distinct migration patterns were observed among the different fixation methods. No differences were found in migration patterns among cemented components in any of the sub-group analyses conducted. For uncemented implants, trabecular metal surfaced components seemed to migrate less than porous-coated or uncoated components Conclusion: Based on the small difference between MTPM values at 6 months and 1 year, MTPM at 6 months could be used instead of MTPM at 1 year for RSA threshold testing. The pooled migration patterns can be used as benchmark for evaluation of new implants by defining fixation-specific RSA thresholds when combined with implant survival.

Directional associations between posttraumatic stress disorder symptoms and cannabis use in young adults: Uncovering variation by sex, race, and ethnicity.

OBJECTIVE: Prevalence rates of cannabis use and PTSD vary, with men reporting greater cannabis use than females, females reporting higher rates of PTSD than males, and race and ethnic minority persons reporting higher rates of both cannabis and PTSD compared to non-Hispanic White individuals. This study extends our understanding of directional associations between cannabis use and PTSD from early to late young adulthood (18-26 years old) using two theoretical models: symptom-driven pathway and substance-induced pathway. METHOD: Participants provided yearly data for 14 years, and the present study utilized data from Waves 9 through 14. Those endorsing Criterion A in at least one wave of data collection (n = 1,454) were included in the analytic sample. We used autoregressive latent trajectory with structured residuals to understand reciprocal associations for the full sample, as well as by sex and race or ethnicity. RESULTS: For the full sample, we noted support for both symptom-driven and substance-induced pathways during early young adulthood (18-20) but only support for a symptom-driven pathway during late young adulthood (21-26). Males showed the same pattern as the full sample; however, for females, only a symptom-driven pathway during late young adulthood was found. For race and ethnic minority participants, we showed full cross-lagged effects during both early and late young adulthood and no associations for non-Hispanic White individuals. CONCLUSIONS: Results indicate that both men and individuals from minoritized racial and ethnic groups are more likely to report heightened PTSD symptomology, maladaptive coping, and worsening symptoms.

A low-dose biplanar X-ray imager has RSA level precision in total knee arthroplasty.

BACKGROUND AND PURPOSE: The low radiation biplanar X-ray imager (EOS imaging, Paris, France) scans patients in a weight-bearing position, provides calibrated images, and limits radiation, an asset for serial radiostereometric analysis (RSA) studies. RSA in vivo precision values have not been published for this type of imaging system, thus the goal of this study was to assess the precision of RSA in vivo utilizing a low radiation biplanar imager. PATIENTS AND METHODS: At a mean of 5 years post-surgery (range 1.4-7.5 years), 15 total knee arthroplasty (TKA) participants (mean age 67 years at the time of imaging, 12 female, 3 male) with RSA markers implanted during index surgery were scanned twice at the same visit in the EOS imager. Precision of marker-based analysis was calculated by comparing the position of the implant relative to the underlying bone between the 2 examinations. RESULTS: The 95% limit of precision was 0.11, 0.04, and 0.15 mm along the x, y, and z axes, respectively and 0.15°, 0.20°, and 0.14° around the same axes. CONCLUSION: This precision study has shown an in vivo RSA precision of ≤ 0.15 mm and ≤ 0.20°, well within published uniplanar values for conventional arthroplasty RSA, with the added benefit of weight-bearing imaging, a lower radiation dose, and without the need for a reference object during the scan.

Continuity of primary care and emergency department visits following knee and hip replacement surgery: a retrospective cohort study.

BACKGROUND: Continuity of primary care (CPC) improves patient well-being, but the association between CPC and surgical outcomes has not been well studied. The numbers of joint replacement procedures are expected to rise considerably in the coming years, so it is crucial to identify factors related to successful outcomes. The purpose of this study was to examine the association between CPC and emergency department (ED) visits after knee and hip replacement surgery. METHODS: Physician claims and hospital data from 2005 to 2020 in Nova Scotia were used in this retrospective study. To measure CPC, we used the Modified Modified Continuity Index (MMCI), which is the number of primary care providers adjusted for the total number of visits. The outcome was ED visits within 90 days of discharge. Logistic regression was used to test for associations between MMCI and the probability of an ED visit. RESULTS: There were 28 574 knee and 16 767 hip procedures in the data set; 13.9% (95% confidence interval [CI] 13.5%-14.3%) and 13.5% (95% CI 13.0%-14.0%) of the patients, respectively, had an ED visit within 90 days. For patients who underwent knee procedures, the mean MMCI was 0.868 (95% CI 0.867-0.870); 10.7% (95% CI 10.4 %-11.1 %) had perfect continuity of care. For patients who underwent hip procedures, the corresponding measures were 0.864 (95% CI 0.862-0.866) and 13.5% (95% CI 13.0%-14.0%). There was a statistically significant negative association between greater continuity of care and the probability of an ED visit after controlling for confounders. CONCLUSION: Having multiple primary care providers before surgery increased the likelihood of negative outcomes following knee or hip replacement surgery compared with having a single provider. Presurgical conversations should include primary care history to improve postsurgical outcomes.

Evaluation of Mental Health First Aid in New York City.

More than 155,000 New Yorkers were trained in Mental Health First Aid (MHFA) between 2016 and 2020. Free citywide trainings were made available to all New Yorkers and were disseminated through city agencies and community-based settings. RAND Corporation researchers conducted a mixed-methods study that included a web-based survey of past trainees and a series of focus groups with leaders of community-based organizations and city agency staff to assess the impact of the MHFA trainings and needs for future training. In this article, the authors describe the evaluation activities that took place; the methods behind them; and the results at the individual, agency, and community levels. They also offer recommendations for ways to improve future mental health education efforts. Respondents applied MHFA skills extensively and broadly across their social networks. Nine in ten respondents had contact with an individual with a mental health problem in the past six months. Among those who had contact, 84 percent indicated using their MHFA skills to help a friend or family member, and nearly half reported applying skills with a co-worker, neighbor, or acquaintance. Because MHFA was offered through city agency workplaces and community-based settings, tens of thousands of New Yorkers were given tools to come to the aid of individuals in their personal and professional lives. MHFA may be a promising approach to building supportive social networks, organizations, and communities that are primed to recognize and assist those experiencing mental health challenges.

Parallel trajectories of vaping and smoking cannabis and their associations with mental and physical well-being among young adults.

BACKGROUND: Vaping and smoking are common modes of using cannabis (THC) among young adults, but little is known about how patterns of cannabis vaping and smoking unfold over time or how using one or both types of products may differently affect mental and physical well-being. This study examines parallel processes of cannabis vaping and smoking over 5 years and mental and physical outcomes in a sample of young adults. METHODS: Annual surveys were conducted between 2016 and 2022 with a mostly California-based cohort of 2428 young adults. Parallel process growth mixture models examined trajectories of past-month frequency of cannabis vaping and smoking from ages 20 - 25. Classes were extracted based on parallel trajectories of vaped and smoked product use. Models assessed differences in self-reported mental (anxiety, depression) and physical (ailments, subjective overall) well-being outcomes in young adulthood across classes, adjusting for demographic characteristics and mental and physical well-being at pre-baseline (average age 19). RESULTS: Four cannabis vaping/smoking classes emerged: low use of cannabis (84.7%), decreasing smoking, low-moderate vaping (7.1%), stable moderate smoking, decreasing vaping (4.6%), and rapid increasing dual use (3.4%). Classes were similar on physical well-being indicators in young adulthood. The rapid increasing dual use class showed higher anxiety and depressive symptoms compared to other classes. CONCLUSION: Progression to higher frequency of both vaping and smoking cannabis in young adulthood may contribute to poorer mental well-being compared to other use patterns. Targeted efforts to reduce dual vaping and smoking in young people who use cannabis may be needed.

Heterogeneity in Unmet Treatment Need and Barriers to Accessing Mental Health Services Among U.S. Military Service Members with Serious Psychological Distress.

The goal of the current study is to examine heterogeneity in mental health treatment utilization, perceived unmet treatment need, and barriers to accessing care among U.S. military members with probable need for treatment. Using data from the 2018 Department of Defense Health Related Behavior Survey, we examined a subsample of 2,336 respondents with serious psychological distress (SPD; past-year K6 score ≥ 13) and defined four mutually exclusive groups based on past-year mental health treatment (treated, untreated) and self-perceived unmet treatment need (recognized, unrecognized). We used chi-square tests and adjusted regression models to compare groups on sociodemographic factors, impairment (K6 score; lost work days), and endorsement of treatment barriers. Approximately 43% of respondents with SPD reported past-year treatment and no unmet need (Needs Met). The remainder (57%) met criteria for unmet need: 18% endorsed treatment and recognized unmet need (Treated/Additional Need); 7% reported no treatment and recognized unmet need (Untreated/Recognized Need); and 32% reported no treatment and no unmet need (Untreated/Unrecognized Need). Compared to other groups, those with Untreated/Unrecognized Need tended to be younger (ages 18-24; p = 0.0002) and never married (p = 0.003). The Treated/Additional Need and Untreated/Recognized Need groups showed similar patterns of treatment barrier endorsement, whereas the Untreated/Unrecognized Need group endorsed nearly all barriers at lower rates. Different strategies may be needed to increase appropriate mental health service use among different subgroups of service members with unmet treatment need, particularly those who may not self-perceive need for treatment.

Does removing menthol cigarettes in convenience stores reduce susceptibility to cigarette smoking? An experimental investigation in young people.

BACKGROUND: Evidence for the effectiveness of menthol cigarette bans comes mostly from studies of adults that smoke. This experiment evaluated whether the absence of menthol products from a convenience store influenced young people's susceptibility to cigarette smoking after they shopped in the store. METHODS: This experiment took place in the RAND StoreLab (RSL), a life-sized research convenience store. A three-group, between-subjects design was used. Study conditions differed in the mix of flavored tobacco products the RSL displayed: 1) All tobacco-, sweet-, and menthol-flavors displayed; 2) only tobacco- and menthol-flavors displayed; and 3) only tobacco-flavors displayed. Participants were randomly assigned to shop in the RSL under one of these conditions and after shopping, completed measures of their susceptibility to cigarette smoking, one measure for menthol cigarettes and one for unflavored cigarettes (scores on each susceptibility measure was dichotomized: 0 = not susceptible; 1 = susceptible). RESULTS: Multivariable logistic regression assessed the main effects of condition on susceptibility to smoking menthol and unflavored cigarettes. There was no condition effect on susceptibility to smoking unflavored cigarettes. However, removing menthol-flavored products significantly increased participants' susceptibility to smoking menthol cigarettes compared to when all flavored products were available (OR = 3.66, 95% CI [1.33, 10.03]). This significant effect was only found among young people with some pre-existing risk of cigarette smoking (OR = 5.92, 95% CI [1.81, 19.39]). CONCLUSION: Results suggest the need to consider that menthol bans could unintentionally increase the appeal of menthol cigarettes among youth already at risk of smoking.
